STEAIVIING-OVEN.

SPECIFICATION forming part of Letters Patent No. 246,585, dated August 30, 1881.

l Application filed .Tune 6, 1881. (No model.) h

To all whom it may concern Be it known that I, EDMUND JORDAN, ot Brooklyn, Kings county, New York, have invented certain new and useful Improvements in Steaming or Cooking Chests or Ovens, of

which the following is a specification.

My invention aims to provide a steaming oven or tank more especially for the steaming of canned goods when placed fresh in the cans,

1o so as to cook, or partly cook, the same and expel the air from the cans previous to sealing the vent-holes thereof. For this purpose it is desirable to have a tank of strong and simple construction, so formed and arranged that it may be readily Opened or closed to quickly admit or remove the cans, and which will heat the same rapidlywhen inserted, and apply the heat economically and in such a way that it may be easily regulated to suit different kinds zo of fruit, vegetables, or meats, each of which generally requires a special temperature and duration of heat for the best effect, and which will also enable such temperature to be automatically maintained as long as desirable for z 5 the proper treatment of each article.

My invention aims to fulfill these conditions, and to this end embodies a number of novel features, as hereinafter fully set forth.

Figure l of the drawings annexed gives a 3o perspective view of my improved steam oven or tank with the door shown partly open, and Fig. 2 is a sectional plan thereof on line a: wot' Fig. l, with the door closed and .held tight by its clamps. Fig. 3 is a detail view of one of 3 5 these clamps; and Figli, afragmentary section ofthe door, showing the attachment of the gasket.

Steam-ovens heretofore made for the special purpose above mentionedsuch as shown in 4o Patent No. 221,294, November 4, l879have usually been cylindrical, placed in upright position, withthe mouth-opening at the top and the lid or cover arranged to lift oft' bodily, the lid being thusrernoved by a crane, by which also the cage containing the cans is lowered into and raised out of the cylinder. The cylindrical form, while favorable to strength, is, however, inconvenient it placed upright with the mouth at the top, and incapacious if placed on its 5o side.

On reference to the drawings it will be obl served that my improved oven, A, is of square or fiat sided form, with its mouth-opening on the side, and is provided with a hinged or swingingdoor,B, which plan is obviously much more convenient and capacious as regards the insertion and removal ot' the canned goods. Thenecessary strength is obtained with this square form by casting the entire oven in one piece, without break or joint, and with deep 6o anges 'a a extending across its flat sides, pret'- erably in diagonal position, as illustrated, whereby the construction is rendered very strong and simple, as will be readily appreciated. The oven is preferably made about thirty-seven inches square or cubic on `its interior, but of course the size may vary, its walls being preferably three-quarters or' au inch thick, smooth ou the inside, but having the stiftening-anges a c on the outside,in about 7o the proportionate thickness and depth shown.

A wide rim or flange, b, surrounds thel mouth of the oven, projecting at right angles with the sides, and in being integral with these walls gives great strength to this part ot' the oven, 75 which would be otherwise weak by reason of the open side or mouth.- A lip, c, rises from this rim around" the mouth, forming the edge of the oven, and this is planed or turned off level and smooth to form a packing-surface for 8o the door to se'at against. In the angle between the lip and flange c b small brackets d d are formed in pairs at intervals around the vrim, as illustrated, and between the same are hinged swinging clamps O, by which the door is clamped tight over the mouth, as shown in Fig. 2. Each clamp consists of an eyebolt, e, the head or eye end of which is socketed between the brackets d d and pivoted thereto by a bolt or pimf, (see Fig. 3,) while the threaded 9o end receives a nut, g, having projecting liandles vh h, w hereby the nut may be forcibly turned when required to clamp the door.

The door B is formed with two projecting eyes, lc k, on its hinging side, and with forked projections Z l on the other sides, corresponding with the several clamps C, as illustrated. The clamps onthe hin ging side of the oven/are engaged with the eyes L kof the door, as illustrated, so that they thus form simple and efroo fective hinges, on which the door can .freely swing, yet also act as clamps to tighten the many advantages, and is not only strong and simple in construction and convenient in operation, but uses the heat economically and enables anydesired temperature to be maintained constantly for any length of time without requiringattention,andthusnotonly saveslabor, butimproves the quality ofthe articles treated, and therebyeffects an importantimprovement.

What I claim isl. A square or hat sided cooking chest or oven adapted to be subjected to internal steampressure, cast in one piece with crossed radial or diagonalflanges which project from the exterior of its Hat sides, substantially as herein shown and described.

2. A square or fiat sided chest or oven, open at one side7 and formed with atlange or rim, b,

' surrounding the same and projecting at right angles from its flat Walls, with crossed radial flanges a a. projecting from the exterior of its fla-t sides or Walls, and the Whole formed in one casting, substantially as and for the purpose set forth.

3. The combina-tion, with a chest or oven, of

on the other side or sides of the lid, substantially as herein shown and described.

4. The combination, with a tank or kettle formed with the projecting mouth-rim b, of the brackets d d, formed on said rim, and swinging clamp-bolts e e, pivoted to said brackets, substantially as and for the purpose set forth.

5. The combination, with a tank or kettle, of a lid or door, B, formed Wit-l1 marginal eyes or forks 7c I, or both,'adapted to be engaged by clamps, and with diametrical flanges n n, radiating from the center-of the lid, or thereabout, to the said eyes and forks, substantially as and for the purpose setforth.

EDMUND JORDAN.
